Hi. I have a Targa DVH-5100x Home Cinema. See Here It has been working perfect up to yesterday when I upgraded to SKY+. I have it connected to SKY+ using Scarts. I use channel AV2 on the sytem to view SKY. But now I just get noise! If I go to CH1 etc, there is sound for BBC, ITV. etc. I'm totally baffled. Can anybody help me out please ?
